This is one of the best product demo's I've seen. The product is just so fully formed, even back in 2008. Really is presented as "it just works".

"Why do you keep sending me this crap" without comment, made me lol.

This video is really great. Lots of easter eggs - including the contents of the pictures and the Dropbox Trade Secrets folder (I laughed hard at "Pets.com Executive Summary.pdf").
